Patented May 24, 1932 STATES UNIT- PAUL J. LAUX, OF SHAVE-RTOWN, PENNSYLVANIA GUARD FOR SPINNING MACHINES Application filed November 18, 1930. Serial No. 496,473.

This invention is a guard for use upon spinning machines. In spinning operations, a row of bobbins are mounted side by side upon the spinning machine and the thread is carried through suitable guides to the bobbin to the wound thereon. Should the thread break or for any other reason fail to wind upon the bobbin in the proper manner, it is very apt to balloon through the action of centrifugal force and become entangled with the thread passingto an adjacent bobbin so that the machine must be stopped and-considerable time lost in restoring normal conditions. is to provide a very simple and inexpensive device which will efficiently prevent the thread becoming entangled with the thread passing to an adjacent bobbin. The inven- 7 tion is illustrated in the accompanying drawings and will be hereinafter fully set forth and particularly defined.

In the drawings: Figure lis an elevation of a bobbin and the parts immediately cooperating therewith with the guard of the present invention in position, and

Fig. 2 is a top plan view of the same. The reference numeral 1 indicates the ring rail which may be of the usual construction and upon which is secured the ring plate 2 mounting the ring 3 about which the traveler 4 will rotate, all these parts being of wellknown construction. The usual bobbin 5 is indicated and is disposed concentric with the ring and the traveler as usual. The present invention provides a guard or shield 6 which is preferably semi-cylindrical in form and set on edge so that it passes at the rear of the bobbin and cooperating parts and extends forward at the opposite sides of the same, as clearly shown in Fig. 2. At its lower end the guard is provided with lugs or brackets 7 which are adapted to rest upon the ring thread passing to an a jacent bobbin.

The object of the present invention may pass as it runs to the bobbin to be wound thereon, the guard being of somewhat greator vertical extent than the bobbin, as shown in Fig. 1.- It will be readily noted that I have provided an exceedingly simple and inexpensive device which will efficiently prevent the thread, when broken or otherwise failing towind properly, becomin entangled with the Inasmuch as the guard extends forwardly at both sides of the bobbin to the front edge of the ring rail, the ballooning thread will be caused to impinge upon the inner surface. of

the guard and bethereby prevented from passing to an adjacent bobbin. Should the traveler break or fly off, it will strike the guard and will rebound to the floor instead of passing to some inaccessiblepart of the machine and being lost. The guard also prevents the oil getting on the silk as it is spun. The guard takes up very little room upon the ring plate and does not interfere in any way with the proper operation of the bobbin.

Having thus described the invention, I claimi A guard for a bobbin of a spinning'ma- I chine consisting of a semi-cylindrical plate passing at the rear and the sides of a bobbin and giving access to the bobbin at the front, said plate being of greater Vertical dimension than a bobbin and provided in its upper edge with a notch to permit thread to pass to a bobbin, and laterally projecting brackets fixed to the lower end of the plate at opposite sides thereof and provided with openings through which fastening devices may be inserted to secure the plate to a rail.

In testimony whereof I aflix my signature.

as indicatedat 8, whereby they may be readily engaged under the heads of securing screws 9 which also serve to secure the ring plate upon I the ring rail. In its upper edge at the back of the bobbin, the guard is formed with a recess or notch 10 through which the thread
